Application iiled April 29, 1920,

To all whom t may concern,.-

Be it known that I, PAUL J. LEMMER, a citizen of the United States,residino' at Groton, in the county of New London, btate of Connecticut,have invented a new and useful Envelop; and I do hereby declare thefollowing to be a full, clear, and exact desoription of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention relates to envelops and has for its object to provide anenvelop to the inner face of which, adjacent its folding point a pieceof tape is adhesively secured and forming means whereby when a pull 1simparted to one end of the tape the flap will be severed from the bodyportion and the envelop opened.

A further object is to provide members, formed from paper which arch thetape and have their ends adhesively joined to the inner face of the flapand forming means whereby, during a fiap severing operation anintermittent jerk will be caused to be imparted to the tape therebyinsuring the severance of the {ia-p.

With the above and other ob'ects in view the invention resides in thecom ination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

Figure 1 is a rear view showing the iap open.

Fig. 2 is a perspective view of a portion of the envelop showing one endof the tape.

Fig. 3 is a detail view of a portion of the envelop showing one end ofthe tape in 'the position itassumes during a flap severing operation.

Fig. 4 is a rear view of an envelop showing a modified form wherein aseries of spaced arching members are adhesively joined to the inner faceof the iap so that an intermittent jerking action will be imparted tothe severing tape duri-ng a Hap severing operation. j

Fig. 5 is a of the envelop detail view of a portion of the Specificationof Letters Patent. Serial No. 377,560.v Renewed March open the envelop.

envelop showing the form of tape used in Fig. 4.

`ig. 6 is a view of another form of envelop showing a perforated flap sothat the flap will easily tear when an instrument or letter opener isplaced under the same.

Referring to the drawings and more especially to Figs. 1,2 and 3 thenumeral 1 designates a conventional form of envelop and 2 the flapthereof. Adhesively secured to the inner face of the fiap 2 is a pieceof tape 3 which tape extends substantially the full length of the Hapand has one of its ends 4 projecting beyond one end of the flap so thatit may be grasped by the fingers of the operator when it is desired tosever the flap and It will be seen that by imparting an upward pull onone end of the tape that the flap will be severed or cut by the tape.

Referring to Figs. 4 and 5 the structure is practically the same as inthe form shown in igs. 1, 2 and 3 with the exception that the tape 3which is adhesively secured to the inner face of the flap 2"L hasarching it a plurality of spaced arching members 3, the ends of whichare adhesively secured to the inner face of the flap 2. The archingmembers 3* perform the function of causing a jerking action during theseverance of the flap thereby insuring a clean cut.

Referring to Fig. 6 it will be seen that the Hap 5 is provided with aseries of perforations 6 adjacent its folding point and whichperforations will cause the flap to be easily severed when a letteropener is placed under the fiap and moved longitudinally with itscutting edge in engagement with the under face of the fiap adjacent theperforations.

From the above it will be seen that an envelo o is provided which may beeasily and quic ly opened and one wherein the cost of making on accountof its simplicity is reduced to a minimum.

The invention having been set forth what is claimed as new and useful isThe combination with an envelop having a iap, of an opener for saidenvelop, sai opener comprising astrip of tape adhesively secured to theinner face of the envelop, transversely disposed, members extendingacross the tape and spaced from each other,

said transversely disposed members being name to this specification inthe presence of dhesivly secnred to the imerbfnce of the two subscribingwitnesses.

for insuring n quick severance. FREDERICK W. HAIs'r,
